Which cost is used on P&L reports when an item goes negative in ConnectStock?

When an item goes negative in ConnectStock, the report uses the most recent cost recorded for that item in ConnectStock at the time of the transaction. This ensures the cost is based on the last known cost, even if inventory temporarily drops below zero.
​
If the user later adds bills or inventory adjustments, ConnectStock will apply that updated cost to the negative transactions and recalculate the P&L accordingly.
